High Performance Power FactorCorrection CapacitorType LKT
Features that matter:
Rated voltage: 400 V, 440 V, 480 V, 525 V, 610 V mainsRated current: > 2 times rated current
> 300 times rated current peakDouble reliability: self-healing at over-voltage peaks
over-pressure disconnectorLowest possiblefailure rate: 200 ppm (parts per million)
ApplicationFRAKO capacitors allow power factor correction installations to beconstructed for any requirement and meet the regulations ofEN 60831-1 and -2 as well as IEC 831-1 and -2. FRAKO holds theManagement System Certificate ISO 9001 and the EnvironmentalManagement System Certificate ISO 14001.
Mechanical ConstructionCylindrical aluminium case, dielectric consisting of metallized polypro-pylene foil.Dry type, filled with a flame inhibiting, stabilized mineral filler.
The dielectric is self-healing. In case of a breakdown caused, for ex-ample, by voltage overload, the self-healing effect takes place.
If the self-healing process does not operate (e.g. because of voltage,current or thermal overload) the cover plate, which is designed as anoverload valve, is raised and ruptures the internal connecting wires tothe coils, so that the capacitor is disconnected from the mains.
DesignCylindrical aluminium case, with mounting stud M 12 x 12. Three-phase capacitors with integrated discharge resistor.
Rating2.5 – 30 kVar at 400 V / 50 Hz

General RemarksFRAKO Power Factor Correction capacitors described in this cataloguerepresent a complete programme of up-to-date technology.We reserve the right to make alterations which are based on newlyacquired knowledge or which contribute to an improvement in ourproducts.
Technical RemarksFor the operation of power capacitors three aspects are of utmostimportance
high overload capacitylong life expectancysafe reaction at overload and during possible breakdowns
FRAKO Power Factor Correction Capacitors are components with avery high power density. 15 kVar reactive power can be housed in1000 cm2. This is achieved by a very low loss factor and high utilizationof the dielectric. However, in order to attain a high life expectancy,partial discharges (these are negligible electrical discharges inside thedielectric) must be surpressed. This is achieved by using a flameinhibiting mineral filler.
Current Load CapacityIn networks polluted with harmonics you can expect overvoltages andin particular a higher RMS current load when resonances occur:
If, for example, approx. 7 % of the 11th harmonic occurs, then thevoltage is 7 % higher; the actual value of the capacitor current, however,is 1.33 times the rated current. For this reason a high current loadcapacity is even more important than the voltage load capacity.At 400 VAC mains voltage FRAKO uses only power capacitor rated at440 VAC. Their permissible current load capacity is:
2 times the rated current at 400 VAC / 50 Hz permanently300 times the rated current at 400 VAC / 50Hz during shortpeak currents

Life ExpectancyExtreme purity of the material used prevents a deterioration of the lossfactor and thereby a reduction of the dielectric strength and the currentload capacity. The very low number of failures in the field prove anexceptional high life expectancy. Field reports received over the last10 years point to a failure rate of less than 1 % in 15 years of operation.
Safety FeaturesFRAKO Power Capacitors offer the highest safety with an overloaddisconnector, which activates at internal overpressure, disconnectsthe capacitor from the mains and thereby prevents capacitordestruction. FRAKO carries out type tests and regular random tests tomonitor the production safety of this function. The test conditionscomply with IEC 831 standards. FRAKO Power Capacitors offer,therefore, the highest possible standard of safety at overload and atthe end of their life time.
Voltage Load CapacityFRAKO Power Capacitors have a load capacity in accordance withEN 60831-1 and -2 as well as IEC 831-1 and -2.
